HIGH5 EnergySource Extreme
EnergySource X’treme is a scientifically formulated carbohydrate and electrolyte sports drink with magnesium and a high caffeine content. X’treme is intended as a one-time caffeine dose. Athletes use it for caffeine loading prior to or during racing and training and towards the end of a long ride. When taking part in tough sports events, caffeine contributes to an increase in endurance performance and capacity¹. That means you can go further than before! It also helps to increase concentration and reaction time².
EnergySource X’treme is the same 2:1 fructose formulation as standard EnergySource, except X’treme contains magnesium and caffeine (140mg/500ml). It is not intended for continuous use during training or an event. Excessive amounts of caffeine can lead to side effects like headache, dizziness and gastrointestinal distress. If you wish to use caffeine continuously throughout your training or event, then switch to EnergySource Plus, which has considerably lower caffeine content (28mg/500ml).
Very occasionally some athletes find that caffeine can increase cramp, so always try in training before racing. If you don’t want to race with caffeine then switch to standard EnergySource.
